DPCT1087

Message

DPC++ currently does not support cross group synchronization. You can specify --use-experimental-features=nd_range_barrier to use the dpct helper function nd_range_barrier to migrate <grid type variable name>.sync().

Detailed Help

By default, the dpct helper function nd_range_barrier is not used to migrate CUDA grid level synchronization. To use nd_range_barrier to migrate CUDA grid level synchronization, specify --use-experimental-features=nd_range_barrier in the migration command.

Suggestions to Fix

Specify --use-experimental-features=nd_range_barrier in the migration command to use dpct helper function nd_range_barrier to migrate CUDA grid level synchronization.
